This game is too difficult for me haha.
Some of the control decisions just seem to me to be a bit arbitrary to add a layer of difficulty to it I would say. I don't see why you would have to manually retrieve the platform extension for example instead of it being automatically spawn back into your inventory once you're done with one level and it readies for you in the next one.
Overall I would say if you simplify the controls and make it challenging instead with the mechanics and level designs it would be a better game.
I did enjoy the audio though!
